ATRAUMATIC SURGICAL EXTRUSION OF COMPLETE CROWN FRACTURED TOOTH USING PERIOTOME IN ESTHETIC ZONE: REPORT OF THREE CASES

BACKGROUND:Restoring traumatically injured teeth is a clinical challenge and often requires a multidisciplinary approach for predictable esthetic outcome.Although a number of techniques have been proposed for clinical crown lengthening procedures, all have some limitations in terms of function and esthetic.AIM: This report presents the clinical and radiographic results of surgical extrusion technique for clinical crown lengthening.MATERIAL & METHODS: Atraumatic surgical extrusion using a specially designed instrument (Periotome) was performed in three cases in which it was expected that extensive respective osseous surgery would have to be used for crown lengthening.After luxation the teeth were extruded to the desired position and stabilized with sutures without rigid splinting.Two months after stabilization the teeth were treated by root canal treatment and firmly restored after 4months.RESULTS: Clinical examination performed after 6 months revealed probing depth ≤3mm around the teeth at all sites without bleeding on probing.Radiographs showed normal periodontal contour with new bone formation in periapical region without any evidence of root or crestal bone resorption or endodontic problems.CONCLUSION: The outcome of the treatment within a short duration has very good results without any esthetic and functional deformities.
